【摘要】 为了解头发微量元素含量与学龄儿童智商之间的关系 ,本文测定了深圳市某小学 5 70名7～ 1 3岁低智商儿童和正常儿童的IQ值及其头发中七种元素 (I、Zn、Fe、Cu、Ca、Mn、Pb)的含量 ,并对低智商儿童及正常儿童头发中的元素含量作了比较。结果表明 ,低智商儿童头发碘、锌、钙的含量显著低于正常儿童头发中的含量 ,而发铅则显著高于正常儿童的含量。说明儿童智商高低与机体碘、锌、钙以及铅的含量有密切关系。更多还原

【Abstract】 In order to find out the relations between the content of trace elements in hair of children and intelligence quotient(IQ),the IQ of 570 children of 7 to 13 years old and the content of trace elements (I,Zn,Fe,Cu,Mn,Pb)in their hair were determined.The content of elements in hair of low IQ children and that of health children was compared.The results showed that the content of I,Zn,Ca in hair of low IQ children was lower than that of healthy children.The content of Pb in hair of low IQ children was higher than that of health children.It indicates that there are close relations between children’s IQ and the content of I,Zn,Ca and Pb in organism.更多还原
